Abstract

The invention discloses a preparation method of a degradable non-woven fabric. The preparation method comprises the following steps of mixing raw materials, specifically, putting toughened polylacticacid fibers, polyester fibers and pineapple leaf fibers into a mixing container according to a mass ratio of (5-7):(2-3):1, injecting deionized water into the mixing container, stirring until the toughened polylactic acid fibers, the polyester fibers and the pineapple leaf fibers are uniformly mixed, fishing out the mixed raw materials, and draining off water; opening, specifically, utilizing an opener to open and scatter the mixed raw materials to prepare mixed fibers; pre-carding, specifically, pre-carding the mixed fibers by using a carding machine; lapping, specifically, conveying the pre-carded mixed fibers into a lapping machine to prepare a composite fiber net; main carding, specifically, conveying the composite fiber net into a main carding machine for secondary carding to obtain an upper-layer thin net and a lower-layer thin net; and hot-pressing and rolling, specifically, conveying the upper-layer thin net and the lower-layer thin net to a heat-sealing forming machine, and rolling and storing the degradable non-woven fabric obtained after heat-sealing operation.

Description

Technical field[0001]The invention belongs to the technical field of non-woven fabrics, and specifically relates to a degradable non-woven fabric and a preparation method thereof.Background technique[0002]Non-woven fabrics, also known as non-woven fabrics, non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. It is widely used in agriculture, industry, sanitation and daily life. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot pressing.[0003]According to the applicant’s research, the following problems exist in the prior art:[0004]The main raw material of non-woven fabrics is polypropylene. However, PP is a linear saturated hydrocarbon, which is difficult to degrade in nature, making the development and production of degradable materials a worldwide environmental issue....
